VIILLIAM D. DESOHAMP, FORT SMITH, ARKANSAS, AND GEORGE C. JONES, OFMQALESTEB, OKLAHOMA; SAID DESOHAMP ASSIGNOR TO SAID JONES.

WELL-DRILLING DERRICK.

To all whom it may concern:

w I Be it known that we, WILLIAM D. Dn-

SCHAMP and GEORGE C. J owns, citizens of the United States, residing,respectively, at Fort Smith, in the county of Sebastian and tate ofArkansas, and McAlester, in the county of Pittsburg and State ofOklahoma, have invented certain new and useful Improvements in'Well-Drilling Derricks, of which the following is a specification.

This invention relates to well drilling machines, and it has for itsobject to provide a derrick of simple and improved construction, whichmay be conveniently transported from place to place and which may bequickly set up for use in the desired location.

A further object of the invention is to provide a derrick of improvedconstruction arranged to carry well drilling machinery and which may beset up close to a building or other similar construction.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of parts,which will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention; it. being. however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may be resorted to when desired.

In the drawings-Figure 1 is a top plan view of a well drilling derrickconstructed in accordance with this invention, the derrick being shownequipped with a well drilling machine. Fig. 2 is a vertical sectionaiview. Fig. 3 is'a detail view in elevation, reduced, of the means forsupporting the outer extremity of the derrick arm.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The improved well drilling derrick is usually supported upon atruck-frame comprising suitably connected sills or side bars 5, 5,supported upon the axles 6, having transporting wheels 7, whereby themachine may be conveniently transported from place to place; but thissupporting truck has not been shown in all the figures of the drawingsin Specification of Letters Patent.

Patented Dec. 2Q, 1910.

Divided and this application filed September Serial No. 519,850.

1 order to bring out more clearly the other parts of the invention.

The base of the machine consists of a circular frame or rim 8, which hasbeen shown as being supported upon cross bars 9, which latter may besupported upon the sills 5 of the truck. The rim or frame 8, supports aplurality of arms or spokes 10, which are mounted upon the upper surfaceof said frame and extend inward in the direction of the center. The rimor frame 8 also supports a plurality of rollers 11, upon which arope-winding drum D is supported for rotation in a horizontal plane. Thedrum 1) is guided for rotation by a circular wheel or rim 12, which isfirmly supported upon the spokes 10, and which supports an internallytoothed stationary spur wheel 13.

The rope-winding drum D is provided upon its upper face with a ratchetwheel 14, the teeth of which project beyond the perimeter of the drum soas to be capable of being engaged by a clutch or locking member to behereinafter described. The said drum is also provided adjacent to itslower edge with a plurality of outward extending ratchet teeth 15, whichare suitably spaced apart and capable of being engaged by a clutch lever16, which is pivotally supported upon one of the spokes 10, which isextended in an outward direction beyond the frame 8, so as to form abracket 17; for the purpose of actuating the clutch lever there isprovided a hand-wheel 18, upon a vertical shaft 19, supported forrotation in bearings 20, and having a crank 21, which is connected by alink 22 with one end of the clutch lever 16; the latter may thus beconveniently manipulated to place its hooked end 23 in the path of theteeth 15, for the purpose of arresting the rotation of the drum; whendesired, the said clutch lever may be moved out of the path of the teeth15 so that it will not interfere with the rotation of the drum.

A circular platform P is provided adjacent to its outer edge with adownward ex tending flange 24, whereby it is supported for rotation uponthe wheel or rim 12, which latter for this purpose is provided with astep or offset 25; metallic wear-plates 26 being mounted upon theopposed faces of the flange 24 and the step 25 for the purpose ofreducing the friction between the parts; it will also be observed thatthe flange 24 is titted within the rope-carryi11g drum 1), so 5 that theparts will be mutually guided tor rotation in an approximately horimntalplane.

It is to be understood that the parts just described are to be taken astypical of any form of well drilling machine and that these and similarparts are herein describeiil for the purpose 01? indicating theapplication of this derrick to use with such a machine. The platform lsupports a derrick- .fraine comprising 'a plurality of inclined beams oruprights 27, the lower ends of which are firmly supported upon theplatform while the up crends of said beams are bolted or otherwisesecured upon a collar 28, having an annular tlanpe 2 resting upon theupper extremities of the beams 27. Fitted in the collar 28 is a ring 30having a flange 31 that engages the tlange of the collar. Firmly boltedor otherwise secured upon the flange 31 of the ring 30 is a derrick-armA, which has been shown as being constructed of beams 32 suitably spacedapart so as to altord bearings for the shafts 33 and 34 near the innerend of said derrick arm, and for a shaft 35, near the outer end of saidarm. The shalts 33, 34, support guidewheels or pulleys 36, 37, and guioewheels or pulleys 88, 39, are likewise supported for rotation upon theshaft 35, said pulleys being utilized for guiding respectively the drillrope and the sand line of the apparatus. The outer cfitreinity of thederrick arm A is firmly supported by suitable braces or uprights lO. itwill be readily obsei ed that the ring 80 constitutes a bearing uponwhich the collar 28 of the derrick-frame is guided for rotation when therotary platform is in motion during the operation of the machine.

The uprights or braces l0 which. serve to support the outer extremity ofthe derrick arm in when the machine is in operation, are pirotallyconnected at their lower ends with a cross-piece ll, adapted to restupon the ground, while the upper ends of said uprights are connectedwith the derrick arm by means of a transverse bolt By this simpleconstruction the derrick arm will be firmly supported; and theconstruction is such that when the machine is not in active use theparts may be disassembled by simply removingthe bolt l2, and theuprights ll) may then be folded adjacent to the cross piece ll, and saiduprights and cross-piece as well as the (lQll'lCl-l-tli'Hl, which lattermay be readily detached from its position on the derrick frame v may bestored upon the axles 6 between the sills 5, 5, of the truck which willsupport the parts also in this manner is being moved from 2. in amachine of the character described, 21 Pltll'illl'lll supported lorrotation in, an a )p oniinately horizontal plane, a derrick t' aniesupported upon the platter-in, and having a l'langed collar at its upperend, a lerrick-arm ha ring a flanged ring engaging; the llallflfllcollar the latter aill ordingr a bcaingr tor the ring, 'nclined uprightsconll( fl0(l detaclnxbly with the derrick-arm adjaceut to the outerextremity of the latter and supporting the same in an approximatelyhorizontal positioin and a crossbar pivotally connected with the lowerextremities of the inclined uprights.
